The Castle of Rocca Calascio is one of Abruzzo's most dramatic ruins, a small stone fortress perched high above the Gran Sasso landscape. Its walls and towers are stark rather than ornate, but the setting makes the place unforgettable.
It is a day trip from L'Aquila rather than an in-town sight. The reward is the combination of medieval stonework, mountain air, and sweeping views over villages, ridges, and open plateau. Weather changes quickly at this altitude, so a clear day makes a large difference.
